Beyond conventional factorization: Non-Hermitian Hamiltonians with radial oscillator spectrum
Ivan Cabrera-Munguia, Oscar Rosas-Ortiz
The eigenvalue problem of the spherically symmetric oscillator Hamiltonian is revisited in the context of canonical raising and lowering operators. The Hamiltonian is then factoriz…

On a static charged fluid around a magnetized mass
I. Cabrera-Munguia, V. S. Manko
We show that any magnetostatic axially symmetric solution of the Einstein-Maxwell equations can be endowed with a specific charged fluid source of the Polanco et al type via a simp…
